I have been attempting to setup an automated testing framework for my job, and nodejs testing has seemed to be the best option for future scalability. Plus, I am attempting to stretch myself into new areas of QA.
I have setup my Nightwatch framework with npm install commands and manually installed the most up-to-date chrome drivers, and selenium standalone executables. I have attempted to ensure that my nightwatch.conf.js file is completely setup to run my first test with google chrome, but I get this error:
⚠ Error connecting to localhost on port 4444.
_________________________________________________
TEST FAILURE: 1 error during execution; 0 tests failed, 0 passed (249ms)

SKIPPED:
- Basic Google search
Which seems to be pretty generic. As per normal Nightwatch setup, I created a root folder called 'Automation' where I stuck my bin folder for the drivers and selenium framework. Inside of the 'Automation' folder I also have my nightwatch.conf.js file that I've setup (Let me know if its more helpful if I paste its code in here). In order to run my test, I use the npx nightwatch command, but I continue to get this error.
From what I can tell it may be due to me trying to run the tests locally, but I can't think of a way that I would configure the selenium service to accept local ports other than how it's been setup.
I don't know if this is a well formatted description of the problem, so I apologize in advance if this is super vague. If there's anything else I can do to help clear it up let me know.
Thank you!

What I will suggest is to create a create a new file for Nightwatch.conf.js and then start adding rest of the configuration from there. Below is an example which works for me:
module.exports = {
src_folders: ["tests"],
skip_testcases_on_fail: false,
page_objects_path: "pageObjects",
custom_commands_path: "./commands",
screenshots: {
enabled: true,
path: "./screenshots",
on_failure: true,
on_error: true
},
test_settings: {
default: {
desiredCapabilities: {
browserName: 'chrome',
chromeOptions: {
prefs: {
download: {
default_directory: require('path').resolve(__dirname + '/download')
}
}
},
},
webdriver: {
start_process: true,
port: 4444,
server_path: require('chromedriver').path,
}
},
test_workers: {
enabled: true,
workers: 'auto'
},
safari: {
desiredCapabilities: {
browserName: 'safari',
alwaysMatch: {
acceptInsecureCerts: false
}
},
webdriver: {
port: 4445,
start_process: true,
server_path: '/usr/bin/safaridriver'
}
},
firefox: {
desiredCapabilities: {
browserName: 'firefox'
},
webdriver: {
start_process: true,
port: 4446,
server_path: require('geckodriver').path
}
}
}
}
The Nightwatch JS, chromedriver, geckodriver are installed using the npm commands. Since I am using a mac I just needed to enable the safari webdriver.
npm install nightwatch --save-dev
npm install geckodriver --save-dev
npm install chromedriver --save-dev
safaridriver --enable

I am trying to run e2e tests for chrome and firefox and I am unable to load the chrome browser with following configuration ,any comment is much appreciated , thanks
var HtmlReporter = require('protractor-beautiful-reporter');

try directConnect: true instead of using seleniumAddress: http://localhost:4444/wd/hub
or make sure your grid server is up and running and also selenium server is up and running
command to start selenium server webdriver-manager start
I am currently trying to set up webdriver and selenium together to run my automation tests through docker but am facing issues. Each time i try to run the tests I get the following error ERROR wdio-runner: Error: connect ECONNREFUSED 127.0.0.1:4444
I am using the selenium/standalone-chrome from docker and can see that the server is configured correctly and running at 127.0.0.1:4444 as I can hit it.
When I try to run webdriver however I seem to face the issue mentioned above. I believe the issue must be something in my webdriver config but having followed the documentation I can't see what's wrong...
const chai = require('chai');
const chaiWebdriver = require('chai-webdriverio').default;
const debug = process.env.DEBUG;
exports.config = {
runner: 'local',

before() {
chai.use(chaiWebdriver(browser));
global.expect = chai.expect;
},
afterTest: test => {
if (!test.passed) {
browser.takeScreenshot();
}
}
};
The versions of the relevant modules:
Selenium-Webdriver: 3.6.0
Protractor: 5.3.0
Firefox: 52.7.2 (32-bit)
IE11
My protractor scripts work smoothly with chrome 65.0.3325.181 (Official Build) (64-bit).
The protractor.conf.js:
exports.config = {
directConnect: true,
seleniumAddress: 'http://localhost:4444/wd/hub',
framework: 'jasmine',
// Spec patterns are relative to the current working directory when
// protractor is called.
suites: {
spec: ['spec/full/example_spec.js']
},
multiCapabilities: [
// {
// browserName: 'chrome',
// chromeOptions: {
// args: ['disable-infobars']
// }
// },
{
'browserName': 'internet explorer',
},
// { browserName: 'firefox' }
],
maxSessions: 1,
}
Is it a bug of the protractor 5.3.0?
I have a Protractor test suite for an application that uses a custom protocol handler to pass messages out of an iOS web view.
When testing it with protractor, how do I prevent the custom window.location = "app://doThing"; message from breaking my tests? It shows the "Open xdg-open?" popup and doesn't continue with tests.
My protractor configuration looks like this:
exports.config = {
...,
multiCapabilities: [ {
browserName: 'chrome',
chromeOptions: {
args: [ '--lang=en', '--window-size=1024x768' ]
},
specs: 'test-*.js',
} ]
};
I achieved this in Chrome 60 by setting the preferences inside the chromeOptions block.
exports.config = {
...,
multiCapabilities: [ {
browserName: 'chrome',
chromeOptions: {
args: [ '--lang=en', '--window-size=1024x768' ],
// Replace "app" with your app's custom scheme.
prefs: {
protocol_handler: {
excluded_schemes: {
"app": true
}
}
},
},
specs: 'test-*.js',
} ]
};
Before Chrome 60, I enforced a profile folder for the Chrome runner. You can do that by having a folder named "/chrome-profile" in the Chrome docker container for example, and adding one file in it named "Default State" with the following content:
{
"protocol_handler": {
"excluded_schemes": {
"app": true
}
}
}
And after that, setting the Chrome user-data-dir flags as such:
exports.config = {
...,
multiCapabilities: [{
'browserName': 'chrome',
'chromeOptions' : {
args: ['--lang=en',
'--window-size=1024,768',
'--user-data-dir=/chrome-profile/']
},
specs: ['test-*.js']
}]
};
